Answer:
341m/s
Explanation:
because speed is given by the product of frequency and wavelength, so mathematically we can write ( v=f×lambda)... so in this case we can say speed=170.5×2= 341m/s
:.speed of the wave= 341m/s
What is the abbreviated electronic configuration of Ca^2+?
Answer:
The electron configuration of a Ca2+ ion is 1s22s22p63s23p6
Explanation:
Answer:
1s², 2s², 2p⁶, 3s², 3p⁶
Explanation:
The general configuration for a regular Calcium atom is :
1s², 2s², 2p⁶, 3s², 3p⁶, 4s²
But it mentions it is a Ca²⁺ ion.
This means it has lost 2 electrons.
Therefore, the configuration is :
1s², 2s², 2p⁶, 3s², 3p⁶
What is the number of moles of ammonia gas formed when 0.5 mole of nitrogen gas is reacted with excess of hydrogen gas?
Answer: 1.5mol NH3
Explanation: 1N2+3H2= NH3
0.5 mol N2x 3NH3/1molN2= 0.5x3= 1.5mol NH3
